[0016] In a preferred embodiment, in step S3, the interface exposure distance is the distance between the insulating materials at both ends of the connection port area;

[0017] The interface exposure distance of each connection port area is measured by a digital rangefinder, and the real-time humidity and interface exposure distance of each connection port area are normalized using the Max-Min algorithm to obtain the real-time temperature normalization result and interface exposure distance normalization result of each connection port area.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The present invention obtains each connection port area of ​​the insulating material in the high-voltage electrostatic discharge device, monitors the real-time temperature of each connection port area, detects the roughness of the connection port area, calculates the dust accumulation index of the corresponding connection port area by comprehensively considering the real-time temperature and roughness of each connection port area, monitors the real-time humidity of each connection port area, calculates the evaluation weight of the corresponding connection port area by comprehensively considering the real-time humidity of each connection port area and the dust accumulation index of the corresponding connection port area, measures the interface exposure distance of each connection port area, generates the risk index of the corresponding connection port area according to the interface exposure distance of each connection port area and the evaluation weight, detects the short-circuit frequency of the connection port area and obtains the default creepage distance of each connection port area, calculates the creepage variation coefficient of each connection port area by comprehensively considering the risk index of the connection port area and the short-circuit frequency of the connection port area, updates the default creepage distance of each connection port area in real time according to the creepage variation coefficient, and adjusts the voltage according to the creepage distance of each connection port area that changes in real time to reduce the breakdown risk of the insulating material.

[0036] Embodiment, a logic control method of voltage ionization based on current magnitude control, such as Figure 1 As shown, the following steps are included:

[0037] Step S1: acquiring each connection port area of ​​the insulating material in the high-voltage electrostatic discharge device, monitoring the real-time temperature of each connection port area, and detecting the roughness of the insulating material at both ends of each connection port area;

[0038] Step S2: Calculate the roughness mean of the corresponding connection port area according to the roughness of the insulating materials at both ends of each connection port area, calculate the dust accumulation index of the corresponding connection port area by using a logistic regression algorithm based on the real-time temperature of each connection port area and the roughness mean, and monitor the real-time humidity of each connection port area;

[0039] Step S3: The evaluation weight of the corresponding connection port area is calculated by using the priority diagram method based on the real-time humidity of each connection port area and the dust accumulation index of the corresponding connection port area, the interface exposure distance of each connection port area is measured, and the risk index of the corresponding connection port area is generated according to the interface exposure distance of each connection port area and the evaluation weight;

[0040] Step S4: Detect the short-circuit frequency of the connector area, calculate the creepage variation coefficient of each connector area by using the geometric mean algorithm based on the risk index of the connector area and the short-circuit frequency of the connector area, obtain the default creepage distance of each connector area, use the creepage variation coefficient to update the default creepage distance of each connector area in real time, and adjust the voltage according to the real-time changing creepage distance of each connector area.

[0041] The specific implementation is as follows:

[0042] In step S1, the historical database is accessed to obtain each connection port area of ​​the insulating material in the high-voltage electrostatic discharge device, the real-time temperature of each connection port area is obtained through a thermocouple, and the two ends of each connection port area of ​​the insulating material in the high-voltage electrostatic discharge device are scanned by a laser scanning instrument to obtain the roughness of the insulating material at both ends of each connection port area;

[0043] The real-time temperature of the connector area and the roughness of the insulation materials at both ends are used to quickly assess the degree of dust accumulation in the connector area;

[0044] The higher the temperature in the connection area, the faster the volatilization speed of the insulating material. When the high-voltage electrostatic discharge device is cooling, the volatilized gaseous substances of the insulating material will re-condense, thus forming dust accumulation in the connection area;

[0045] The higher the roughness of the insulating material at both ends of the connection area, the stronger the surface adhesion, and the easier it is to generate static electricity. Strong adhesion makes it easier to capture dust particles, and static electricity easily attracts dust and pollutants in the air, causing dust accumulation in the connection area.

[0046] It should be noted that the historical database is a system that stores historical data and event information. It is used in the above to obtain the various connection areas of the insulating material in the voltage electrostatic discharge device in the historical records; the thermocouple is a temperature sensor used to monitor the real-time temperature of each connection area; the laser scanner is a device that measures the three-dimensional shape and characteristics of the surface of an object, and can automatically calculate the surface roughness of the object. In this example, it is used to obtain the roughness of the insulating material at both ends of each connection area.

[0047] In step S2, the average roughness of the insulating material at both ends of each connection port region is calculated as the roughness mean of the corresponding connection port region, and the real-time temperature of each connection port region is labeled using the Max-Min normalization algorithm: nore =xx min / x max -x min , where x is the real-time temperature of each connection port area, x nore is the real-time temperature normalization result of the corresponding connection area, x max is the maximum real-time temperature of all connection ports, xmin It is the minimum real-time temperature of all connection port areas.

[0048] The dust accumulation index of the corresponding connection area is calculated by combining the real-time temperature normalization results and the roughness mean of each connection area using a logistic regression algorithm: C = 1 / 1 + e -z , where e is the natural base, z is the logistic regression parameter and z is the sum of the real-time temperature normalization result and the roughness of each connection port area, and C is the dust accumulation index of the corresponding connection port area.

[0049] Use humidity sensors to monitor the real-time humidity of each connection port area. The higher the humidity in the connection port area, the more water molecules there are. Water molecules are ionized under the action of the electric field. The generated ions will increase the conductivity of the gas, thereby increasing the risk of electricity consumption in the connection port area.

[0050] It should be noted that the Max-Mix normalization algorithm is a data preprocessing method used to scale the eigenvalues ​​to a specific range for easy analysis and processing; the humidity sensor is a device that measures the water vapor content in the air, and in this example is used to monitor the real-time humidity of each connection port area.

[0051] In step S3, the dust accumulation index of the connection port area reflects the degree of dust accumulation in the connection port area. The higher the degree of dust accumulation in the connection port area, the more current conduction paths will be formed, which increases the flow of current and thus increases the risk of electricity use in the connection port area.

[0052] The interface exposure distance is the distance between the insulating materials at both ends of the connector area, that is, the exposed length of the wire. The larger the interface exposure distance, the larger the dust accumulation in the connector area, the larger the conduction path formed, and the easier it is to contact more water molecules in the nearby air, resulting in an increased risk of electricity use in the connector area.

[0053] The interface exposure distance of each connection port area is measured by a digital distance meter, and the real-time humidity and interface exposure distance of each connection port area are normalized using a Max-Min normalization algorithm to obtain the real-time temperature normalization result and the interface exposure distance normalization result of each connection port area;

[0054] The real-time temperature normalization result of each connection port area and the dust accumulation index of the corresponding connection port area are summed as the weight index of the corresponding connection port area;

[0055] The weight index of each connection port area and the standardized result of the interface exposure distance are combined to calculate the evaluation weight of the corresponding connection port area using the priority diagram method. The specific steps are as follows:

[0056] The standardized results of the interface exposure distance of each connection port area are weighted as shown in Table 1 below:

[0057]

[0058] Table 1

[0059] It should be noted that the A, B, and C regions in Table 1 are three connection port regions listed in this embodiment. After sorting the connection port regions according to the weight index, they correspond to the A, B, and C regions in descending order.

[0060] The standardized result of the interface exposure distance of each connection port area is multiplied by the assessment weight of the corresponding connection port area, and the product result is used as the risk index of the corresponding connection port area.

[0061] It should be noted that the digital rangefinder is a device for accurately measuring distances. It uses laser and ultrasonic technology to obtain measurement results. In this example, it is used to measure the interface exposure distance of each connection area. In the above, only three connection port areas are used for distance measurement. As the connection port areas increase or decrease, the evaluation weights of different connection port areas will be automatically adjusted, which will not be elaborated here.

[0062] In step S4, a period of time is selected as the analysis time, the number of short circuits in each connection port area is counted during the analysis time, the current in each connection port area is monitored in real time using a current detector, the short circuit count of each connection port area is initialized to 0, and when the current in the connection port area exceeds a preset current threshold during the analysis time, the short circuit count is increased by 1, and the short circuit count of each connection port area during the analysis time is counted;

[0063] It should be noted that the current detector is a device for measuring current, and in this example is used to monitor the current in each connection port area in real time.

[0064] Select the maximum short-circuit count value of all the connection port areas, and use the ratio of the short-circuit count value of the connection port area to the maximum short-circuit count value as the short-circuit frequency of the corresponding connection port area;

[0065] The geometric mean algorithm is used to calculate the creepage variation coefficient of each connector area based on the risk index of the connector area and the short-circuit frequency of the connector area. The formula is: Wherein, a is the risk index of the connector area, b is the short circuit frequency of the corresponding connector area, and p is the creepage variation coefficient of the corresponding connector area.

[0066] The average creepage variation coefficient of all connector areas is calculated, and the ratio of the creepage variation coefficient of the connector area to the average creepage variation coefficient of the connector area is used as the adjustment ratio of the corresponding connector area.

[0067] Creepage distance refers to the shortest distance of the current path creeping along the surface of electrical equipment or insulating materials. The larger the creepage distance, the better the insulation performance of the insulating material and the higher the safety of electricity use.

[0068] Access the historical database to obtain the default creepage distance of each connector area, and divide the default creepage distance of each connector area by the adjustment ratio of the corresponding connector area to obtain an updated creepage distance;

[0069] It should be explained that, because the adjustment ratio is updated in real time, the creepage distance of each connection port area is also updated in real time.

[0070] The specific steps to adjust the voltage according to the creepage distance of each connection port area are as follows:

[0071] A period of time is set as the adjustment time for timing, the average creepage distance of each connection port area within the adjustment time is calculated, the discharge current of the discharge needle and the zero plate is calculated by the charging module, the voltage reduction standard is obtained by multiplying the average creepage distance of each connection port area by a preset voltage conversion coefficient, the discharge current of the discharge needle and the zero plate is compared with a preset comparison threshold, and adjustment is made according to the voltage reduction standard;

[0072] When the discharge current is lower than the comparison threshold, no adjustment is made; when the discharge current is higher than the comparison threshold, the voltage reduction standard is subtracted from the current voltage, and then the discharge current and the comparison threshold are compared, and repeated adjustments are made until the discharge current is lower than the comparison threshold, and the final voltage value is used as the current voltage of the high-voltage electrostatic discharge device.

[0073] For example, the comparison threshold is 2uA, and the voltage reduction standard is 200V. When the discharge current of the discharge needle and the zero plate is higher than 2uA, the current voltage is subtracted by 200V and a cyclic judgment is performed until the discharge current is lower than 2uA and the adjustment is stopped.

[0074] It should be noted that the discharge needle and the zero plate are components in electrical engineering and high-voltage electrical experiments, which are used to study and test discharge and determine the output of the equipment; the comparison threshold and voltage conversion coefficient mentioned above are set by professionals in this field according to actual conditions. At the same time, multiple humidity thresholds can also be set for enhanced control, and the voltage reduction standard is multiplied by the reduction ratio to achieve precise adjustment of the voltage. For example, the humidity threshold is set to 90% and 80%, and the reduction ratio is 0.5. When the humidity at the detection point reaches more than 90% of the historical maximum humidity of the detection area, the current voltage is subtracted by 200V and a cyclic judgment is performed; when the humidity at the detection point reaches between 80% and 90% of the historical maximum humidity of the detection area, the current voltage is subtracted by 100V and a cyclic judgment is performed; when the humidity at the detection point reaches 80% of the historical maximum humidity of the detection area, no voltage adjustment is performed.
